Hi Boris,
When you are running the memory test make sure Data cahe and Instruction
caches are enabled.
Also check your BAT setting, there also Cache enable BIT shall be set.
As the burst transcation will happen only when cache is enabled.
How abt ECC...?

Hi,
We need to findout where is the bottlenect.
1. Run vmstat on the ML403 board and find out the percentage CPU is busy
when you are transferring the file. That will show if cpu is busy or not.
2. Run oprofile and find out which are the routines eating away the cpu
time.
Once we have data
in each trial. But in none of them it jumped to interrupt
handler.
Please let me know whether this is the one you said to try or anything
else. ?
Thanks

Hi Sudhir,
From the PCI dump it looks like IRQ PIN register is 0. During enumeration
when BIOS sees that IRQ PIN register is 0, it would not allocate any
interrupt for this card and that's why you are seeing IRQ Line register also
as 0 value.
We need to do some work around for this.
